Abstract:
PROBLEM TO BE SOLVED: To provide an improved pressure vessel.SOLUTION: The invention relates to a fiber-reinforced pressure vessel (1, 6) comprising a rigid gas- or fluid-tight body (2, 7, 13, 19) overwound with fiber filaments (3, 10, 11, 18), where the fiber filaments are wound such that at least a number of fiber filaments can freely move with respect to one another and such that when the pressure vessel is under internal pressure the fiber filaments are deformed precisely in their longitudinal direction. The invention also relates to a method of manufacturing the fiber-reinforced pressure vessel in which no matrix material (for example, resin) incorporating at least a number of fiber filaments is used for a section of the pressure vessel where the fiber filaments can freely move with respect to one another.
Abstract:
A pressure vessel and a system of a vehicle with such a pressure vessel, wherein the pressure vessel is suitable for storage of pressurized fluids, comprising a housing which extends along a longitudinal axis. The housing defines an inner volume. The shape of the housing, in longitudinal cross-section, is defined by the circumference of a set of circles. The set of circles comprises a central circle, with a center point which is defined by the longitudinal axis, and four primary peripheral circles each of which intersects with the central circle at two points. The primary peripheral circles are axially distributed on the central circle in opposing pairs.

Abstract:
The invention relates to a method for forming a fibre reinforced pressure vessel having at least one fastener for fastening an element to an outside of the pressure vessel. The method comprises a step of providing a semi-finished fibre reinforced pressure vessel having a cover layer comprising a rubber or rubberlike material, preferably a material comprising and/or being formed at least partly by a polyurethane material and/or an elastomer material. The method further comprises a step of forming a fastener for fastening an element to the outside of the pressure vessel, by moulding said fastener onto the cover layer, wherein said fastener is moulded from a substantially liquid rubber or rubberlike material.
Abstract:
Vessel, comprising a substantially fluid tight liner provided with a layer of fibre material, and a mount for mounting appendages to the vessel. The mount comprises a substantially cylindrical neck portion with a radially outwardly extending base flange. The base flange is axially fixedly but rotationally free held between the liner and the layer of fibre material.

Abstract:
A high pressure tank (10) including a plastic liner (12) with a metallic boss (14), a winded layer of dry fibres of a first type (16), a winded layer of dry fibres of a second type (18); the winded layer of dry fibres of the first type (16) being sandwiched between the plastic liner (12) and the winded layer of dry fibres of the second type (18); the dry fibres of the first type having a higher abrasion resistance than the dry fibres of the second type; the winded layer of dry fibres of the first type (16) not adhering to the plastic liner (12) and the metallic boss (14); the high pressure tank (10) having a nominal working pressure equal to or greater than 200 bar.
